An industrial plant has two reservoirs that are used to temporarily store fluid $A$ and fluid $B$. Each reservoir is equipped with two sensors: one detects the incoming flow rate and the other detects the fluid level. Assume the flow rate sensor outputs are low when the flow rate is satisfactory and high when the flow rate is too high. In addition, assume the fluid level sensor outputs are low when the fluid level is satisfactory and high when the level is too high. Design a detector circuit that will produce a high output whenever the fluid level in either or both reservoirs is too high and the flow rate for either of both reservoirs is too high.

Key Concepts

Combinational Circuit Design

Combinational circuit design focuses on creating circuits where the output is solely determined by the current inputs, without any memory elements. This approach is critical in applications requiring immediate responses to certain conditions, such as in fault or alarm detection systems.

Boolean Algebra

Boolean algebra provides the mathematical framework for expressing and manipulating binary variables using operations like AND, OR, and NOT. It is fundamental in designing digital circuits by allowing complex logical conditions to be simplified and efficiently implemented.

Logic Gates

Logic gates are the basic components used to implement Boolean functions in hardware. They execute operations such as AND, OR, and NOT, which are used to combine sensor signals and create decision-making circuits in digital system designs.

Sensor Integration

Sensor integration involves combining multiple sensor outputs to monitor and control systems effectively. This concept is important as it encompasses the methodology of fusing different binary signals (e.g., from sensors measuring various parameters) to trigger appropriate responses.

Threshold Detection

Threshold detection is the process of comparing measured sensor values against predefined criteria to generate binary signals. This allows for the system to discern when certain conditions are met (such as an excessive level or rate), facilitating automated response mechanisms.
